Detailed Description

A node handle used when a value is kind::object to access elements of the object in potentially destructive manner.

This makes it possible to modify the contents of a node extracted from an object, and then re-insert it without having to copy the element.

Member Typedef Documentation

◆ key_type

using jsonv::object_node_handle::key_type = std::string

Member Function Documentation

◆ empty()

bool jsonv::object_node_handle::empty ( ) const

inlinenoexcept

Returns: true if the node handle is empty; false if otherwise.

Definition at line 1252 of file value.hpp.

◆ key()

key_type & jsonv::object_node_handle::key ( ) const

Returns a non-const reference to the key_type member of the element.

Exceptions

std::invalid_argument if the node handle is empty.

◆ mapped()

mapped_type & jsonv::object_node_handle::mapped ( ) const

Returns a non-const reference to the mapped_type member of the element.

Exceptions

std::invalid_argument if the node handle is empty.

◆ operator bool()

jsonv::object_node_handle::operator bool ( ) const

inlineexplicitnoexcept

Returns: false if the node handle is empty; true if otherwise.

Definition at line 1256 of file value.hpp.

◆ operator=()

object_node_handle & jsonv::object_node_handle::operator= ( object_node_handle && src )

noexcept

Release the element this handle owns, if any, and take over the one owned by src, if any.

src is left empty. Self-assignment has no effect.
